Field notes
The calculator menu is grouped by shop task, including troubleshooting, tooling, inspection, assembly, and quoting. Individual entries describe specific inputs and outputs: the sine-bar tool estimates a gauge-block stack for a 5-inch or 100 mm bar, while the bend-allowance tool can derive a K-factor from a test bend. These are homepage descriptions; the extracted page does not establish that each calculator was exercised.
